Abstract

A vehicle seat includes a seat component member that has a frame member, a cushion material, and a support member arranged on the frame member. The support member includes a frame-shaped member having a polygonal shape that can be attached to the frame member, and a bag-shaped planar member that is attached to the frame-shaped member in a tensioned state to support the cushion material. The frame-shaped member can be accommodated in the bag-shaped planner member while at least one side of the frame-shaped member is at a contracted state. The frame-shaped member is maintained at an expanded state as the at least one side of the frame-shaped member is at a non-contracted state, such that the planner member is expanded from an inner side thereof and is maintained at the tensioned state.

Claims

1. A vehicle seat comprising:

a seat component member which is a seat cushion or a seat back, the seat component member including;

a frame member configuring a seat frame;

a cushion material configuring an outer shape of the seat and capable of elastically supporting a passenger; and

a support member arranged on the frame member and capable of supporting the cushion material, the support member including a frame-shaped member having a polygonal shape that can be attached to the frame member, and a bag-shaped planar member that is attached to the frame-shaped member in a tensioned state to support the cushion material,

wherein the frame-shaped member can be accommodated in the bag-shaped planner member while at least one side of the frame-shaped member is at a contracted state, and

wherein the frame-shaped member is maintained at an expanded state as the at least one side of the frame-shaped member is at a non-contracted state, such that the planner member is expanded from an inner side thereof and is maintained at the tensioned state.

2. The vehicle seat according to claim 1,

wherein the support member includes a restraint member that is attached to the frame-shaped member covered with the planar member to restrain a relative movement between the frame-shaped member and the planar member.

3. The vehicle seat according to claim 1,

wherein the support member includes a pair of divided end portions formed by partially dividing the frame-shaped member, and a connection member that connects the pair of divided end portions, and

wherein when the pair of divided end portions are made close to each other, the frame-shaped member becomes the contracted state, and the frame-shaped member is maintained at the expanded state by connecting the pair of divided end portions with the connection member while the pair of divided end portions are spaced from each other.
